downloaded had no reg defs for AMD's new registers. I'm running
64-bit OpenBSD).

Fasm:

Or Yasm:

Note that (G)as has got an ".intel_syntax" option that you also might like.

Yasm is now built and running as a 64-bit program on OpenBSD 3.9.
I have linked a test yasm program with a C test program.
The program aborts with a segfault when the first assembly instruction
is executed. Gcc disassembles the code ok, so I think the problem is
incorrect section attributes (currently just .text) for the yasm
assembly code. Anyone know what I'm still missing?

Thanks,
